CORN-SHELLER.

SPECIFICATION forming part of Letters Patent N 0. 675,452, dated Jun' 4,1901.

Application filed May 9, 1900. Serial No. 16,006. (No model.)

To (all whom it may concern:

Be it known that LJOHN V. STRADLEY,a citi- Zen of the United States ofAmerica, residing at Greenwood, in the county of Cass and State ofNebraska, have invented certain new and useful Improvements inCorn-Shellers, of wihch the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to corn-shellers, and particularly to that classin which revolving cylinders are employed in connection with a concaveor breasting; and it has for its primary object the provision of meanswhereby the corn is effectually shelled.

A further object of the invention is to provide, in combination with thecylinder, a breasting and grate whereby the cob after traveling betweenthe breast and cylinder is deposited on the grate and finallydischarged.

Furthermore, the object of the invention is to provide a grate and incombination therewith novel means whereby its inclination may be variedwith relation to the cylinder with which it coacts.

Furthermore, the object of the invention is to provide novel means foraffording a yielding action of the grate and in the provision ofmechanism for adjusting the tension of said yielding means.

With the above and other objects in view the invention consists in thedetails of con struction and in the arrangement and combination of partsto be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings, forming part of this specification,wl1erein likecharacters denote corresponding parts in the several views, and in whichFigure 1 is a top plan view of the invention. Fig. 2 is a cross-sectionon line 2 2 of Fig. 1, and Fig. 3 is a side view in elevation and partlyin section.

In the drawings, 1 indicates a frame of any ordinary construction, and 2a cylinder suitably journaled and having teeth 3 of convenient form onits surface.

Stationed at the rear of the cylinder, a suitable distance therefrom, isa breasting 4,having its inner surface concaved, said breastinghavingone end secured to the frame in any suitable manner-as, for instance, bya screw ap -and its opposite end secured to a standard 5 of the housing6 by a screw I). This housing is also provided with a standard 7, havinga foot 8 formed integral therewith, said foot bearing against the frameand being secured thereto. Secured near the top on the inner surfaces ofthe standards are horizontallydisposed ribs 9 for the purpose to behereinafter set forth. Within this housing is a cob-grate 10, consistingof a series of concaved ribs 11, a series of crossstrips 12, and a plate13 at the top, all formed integral with the ribs. The lower cross-stripis provided with apertured lugs 14, which receive the pivot 14 of therod, to be hereinafter described. Near the top the ribs have apertures15, adapted to receive a cross-bar 16, which extends beyond the sides ofthe grate and is adapted to bear against the upper surfaces of the ribs9 for supporting the grate. Eyebolts 17 are secured to the crossbar 16ofthe grate and have their free ends passing through apertures 18 in therear of the housing. A rod 19 is secured at one end on the pivot of thelugs 14: and has its free end passing through the frame at 20. Threadedon the free ends of the eyebolts 17 are hand-wheels 21 and lock-nuts 22.On the outer end of the rod 19 is threaded a nut 23 and a spring-key 24,which passes through both the nut and rod. Approximately midway of therod 19 are threaded a hand-wheel 25 and a lock-nut 26, and bearingbetween the wheel 25 and an apertured plate 27, bolted to the frame andregistering with the aperture for the rod, is a spring 28. A drum 29 isfastened at the top of the breastin g and laps over the cylinder and isbolted to the frame. A hopper 30 is provided at one end of the cylinder,and it will be understood that operat ing means for the cylinder will beused.

The operation of the device is as follows: Corn is fed to the machinethrough the hopper 30 and is engaged by the teeth 3 of the revolvingcylinder 2 and is carried along under the drum 29. \Vhen nearly all ofthe corn has been shelled, the cob is discharged between the breastingand the cylinder. What corn is left on the cob is shelled while passingdown around the cylinder and against the grate.

In order to meet the varying conditions, the grate is adjustable bymeans of the bolts 17 and the rod 19, and is held in its adjustedpositions by means of the hand-wheels 21 and nut 23, and in order thatthe cobs may have free exit atension 28 is employed,which may be variedby means of the wheel 25.

At a suitable distance below the sheller is placed a separating-table ofany preferred construction, the object of which will be fully understoodby those familiar with the art.

It will be remembered that changes in the proportions and details ofconstruction may be resorted to without departing from the spirit orscope of the invention, and it is thought that the minor details ofoperation willbe fully understood from the foregoing description.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is"- r 1. In combination, a frame, asuitable cylinder, a housing supported by two standards, one of saidstandards having a foot adapted to bear against and be secured to theframe, ribs on the inner surfaces of the standards near the top, a grateconsisting of a series of ribs and cross-strips supported within thehousing, and a breasting having one end secured to the frame and theother to the housing, as and for the purpose set forth.

2. In combination, a frame, a suitable cylinder, a housing supported bystandards, ribs on the inner surfaces of the standards near the top, agrate consisting of a series of concaved ribs and cross-strips securedwithin the housing, a breasting suitably placed with relation to thecylinder, and means whereby the grate is adjusted, as and for thepurpose set forth.

3. Ina corn-sheller the combination of a frame, a suitable cylinder,a'housing supported by standards, a grate consisting of a series ofconcaved ribs and cross-strips, said ribs having apertures near the top,ribs on the inner surfaces of the standards near the top, a cross-rodpassing through the apertures of the ribs of the grate and adapted tobear against the upper surface of the ribs of the standards, and aconcaved breasting suitably placed with relation to the cylinder, as andfor the purpose set forth.

4. In a corn-shelter a housing supported by standards, said standardshaving ribs on their inner surfaces near the top, a grate consisting ofa series of concaved ribs and crossstrips, a cross-strip adapted to passthrough apertures in the ribs of the grate and to bear against the uppersurfaces of the ribs of the standards, apertured lugs projecting fromthe lower cross strip, eyebolts secured to the cross-bar and havingtheir free ends passing through apertures in the rear of the housing,

a rod pivotally secured to the apertured lugs .of the grate and havingits free end passing through an aperture of the frame, securing means onthe end of the eyebolts and rod, and means on the rod whereby a tensionis allowed.

5. In a corn-sheller, a housing suitably supported by standards, saidstandards having ribs on their inner surfaces near the top, a grateconsisting of a series of concaved ribs and cross-strips within thehousing, said concaved ribs having apertures near the top, a

cross-rod through the apertures adapted to bear against the uppersurfaces of the ribs of the standards, apertured lugs projecting fromthe lower cross-strip, eyebolts secured to the cross-bar and havingtheir free ends passing through apertures in the rear of the housing, arod pivotally secured to the lug of the grate and having its free endpassing through an aperture in the frame, hand-wheels threaded on thefree ends of the bolts and adapted to bear against the outer surface ofthe rear of the housing, lock-nuts also threaded on the free ends of thebolts, a nut threaded on the free end of the rod, a spring-key passingthrough both the nut and rod, a tension on the rod, and means wherebythe tension may be varied.

6. In a corn-shellcr, a housing suitably supported by standards, saidstandards having ribs on their inner surfaces near the top, a grateconsisting of a series of concaved ribs and cross-strips within thehousing, said concaved ribs having apertures near the top, a cross-rodthrough the apertures adapted to bear against the upper surfaces of theribs of the standards, apertured lugs projecting from the lowercross-strip, eyebolts secured to the cross-bar and having their freeends passing through apertures in the rear of the housing, a rodpivotally secured to the lugs of the grate and having its free endpassing through an aperture in the frame, hand-wheels threaded on thefree ends of'the bolts and adapted to bear against the outer surface ofthe rear of the housing, lock-nuts also threaded on the free ends of thebolts, a nut threaded on the free end of the rod, a spring-key passingthrough both the nut and rod, a hand-Wheel threaded on the rodapproximately midway of its length, a lock-nut for the Wheel, anapertured plate bolted to the frame and registering with the aperturefor the rod, and a spring on the rod abutting the Wheel and plate, asand for the purpose set forth.
